La TRAVIATA
At one of her brilliant supper parties, the beautiful Violetta Valéry, meets the well-born Alfredo Germont, and for love of him abandons her feverish life of pleasure. Alfredo’s father intrudes, demands that Violetta renounce Alfredo. Violetta determines to make the sacrifice and departs, leaving only a note for Alfredo. She appears at a ball on the arm of an old admirer, Baron Douphol, to the fury of Alfredo. The two men play at cards; Alfredo wins consistently. Unable to persuade Violetta to go with him, Alfredo insults her and is challenged by the Baron. Violetta becomes ill, and all her friends desert her, leaving her virtually penniless. Alfredo at last returns. His father has told him of Violetta’s noble renunciation, and urged him to seek her forgiveness. Overjoyed at the sight of him, Violetta attempts to rise. But it is too late. As Germont and the doctor enter, Violetta dies in Alfredo’s arms.
